Thank you for your reply.
1. That is better but there should also be a select all button as it is time consuming to turn all off if you are only looking for one of the taxonomies. Is there a way to do this?
2.) I have turned off the taxonomies in source 2 page yet it is still not returning the results which should only be portfolio posts – as selected in source 1.
3.) how long before this update becomes available?
4.) a date filter is a very NB filter for searching posts, I wont be able to use this plugin without being able to search the date, how long before this update?
